Worked on accessibility enhancements for the securityscorecard/design-system repository, focusing on improving the usability and compliance of UI components. Addressed accessibility requirements by adding ARIA attributes and roles, such as aria-hidden on icons in HintTooltip, role=tooltip for Tooltip, and aria-invalid and aria-disabled on TextArea. Utilized React with JavaScript and TypeScript to implement these changes, ensuring components met accessibility linting standards by reordering JSX attributes as needed. The work improved keyboard and screen reader support, reducing user experience barriers and aligning the design system with accessibility best practices. No bugs were fixed during this period, with efforts centered on feature delivery.
